Description

    FIELD OF THE INVENTION
  • The invention relates generally to a tailgate extension system that provides the sporting enthusiast diversified recreational options related to various sporting activities and a unique method of providing most house hold facilities for outdoors camping and entertainment. In particular, the invention relates to vehicle mounted observation and platforms and outdoor equipment. [0001]
  • BACKGROUND OF THE INVENTION
  • Outdoor sporting enthusiasts occasionally require an elevated platform to pursue sporting interests. For example, hunters use elevated stands in the woods from which to view and hunt for game animals, such as deer or elk. Such an elevated platform shields the hunter from the general viewing area of wild game animals, enabling him or her to enjoy a full view of approaching game from a relatively long distance. [0002]
  • It is also common for spectators at sporting events such as parades, rodeos, bird watching, motor races and the like to erect temporary structures that enable the spectator to view the sporting activity from an elevated position. In viewing such sporting events, the elevated position of the spectator provides for a better view of the action. Furthermore, the view from an elevated position, being generally above the crowd and noise, facilitates an unobstructed and enjoyable position from which to view the event. [0003]
  • Unfortunately, such structures are difficult and cumbersome to move from one place to another. Also, such structures are heavy, and difficult to erect, which causes them to be less convenient. Many scaffolds and the like require several people several hours to assemble, reducing their utility for sporting events. [0004]
  • Portable tree stands and the like for hunting are known, but many of these stands require, prior to the hunt, significant effort to erect and maintain them for later use during hunting hours. Furthermore, many such stands are designed to be relatively permanent fixtures on the land. For hunters using leased or borrowed land, or hunting on government property, a hunting stand that is mounted in the earth or on a tree usually is not a viable legal option. [0005]
  • Mobile hunter stands that mount in the bed of a pickup truck are known. For example, U.S. Pat. No. 5,881,839 is directed to a hunter's stand that is mounted inside the bed of a pickup truck. In the collapsed position, the stand is lower than the upper level of the truck cab, and in that position the truck may be driven to the desired destination at normal speeds. Then hunter's stand may be erected by one person in the back or bed of the pickup truck, and is ready for use. Then, after the hunting is event is completed, the stand may be collapsed to enable the truck to move to another site, or to drive to overnight accommodations. [0006]
  • The assembly shown in the U.S. Pat. No. 5,881,839 occupies the bed of the pickup truck during the hunting season, and at the end of the season, the stand may be taken out truck bed by removing bolts from the bed of the truck, and lifting the entire stand assembly out of the truck bed, for storage away from the truck. When mounted in the truck, however, the feet of the stand are bolted to the bed of the truck to secure the stand in position. [0007]
  • There are several disadvantages to the apparatus disclosed in U.S. Pat. No. 5,881,839. For example, the apparatus as shown occupies most of the space in the bed of the pickup truck, which leaves little or no space for other gear and equipment that the hunter may wish to transport to the hunting site. Furthermore, the apparatus is not designed for use with vehicles other than pickup trucks with cargo beds, and cannot easily be used with other vehicles such as sport utility vehicles, or passenger cars. Thus, the design limits its overall applicability. The task of unbolting and manually removing the apparatus from the pickup truck bed is a fairly labor intensive and time consuming process, which makes it unlikely that a hunter would be able to conveniently remove the stand from the pickup truck on non-hunting weekends during the hunting season without expending time and effort to do so. [0008]
  • What is needed in the industry is a method and apparatus for supporting one or more persons in an elevated position on a secure platform. An apparatus that is connected to a vehicle, and is therefore mobile, is desirable. Furthermore, an apparatus that provides for a safe and relatively high vantage point, while still affording convenience to the user would be helpful. Furthermore, a stand that may be efficiently and easily transported by common pick-up trucks, sport utility vehicles, and the like, and then erected in connection with such vehicles, would be highly desirable. [0009]
  • SUMMARY OF THE INVENTION
  • The present invention relates to an improved observation platform apparatus and method that maybe removably installed upon a vehicle, such as a transport utility vehicle. [0010]
  • Accordingly, one of the objects of the invention is to provide an improved observation platform structure that may be installed, and easily removed, from a sport utility vehicle without modification of the vehicle. [0011]
  • Another object of the invention is to provide an observation platform that may easily be installed upon a vehicle, and when transitioned into a transport mode, may be easily transported to a hunting site, sporting event site, or other location. [0012]
  • A further object of the invention is to provide an observation platform or hunters stand that may be installed upon a vehicle, but may be erected to a suitable height for hunting once the vehicle is located a remote hunting site. [0013]
  • It is a further object of the invention to provide an observation platform that may be collapsed and then transported by way of the standard 2-inch trailer hitch on a vehicle at regular highway speeds to and from a remote hunting area. [0014]
  • It is a further object of the present invention to provide an observation platform that may be erected, or collapsed, by one person without complex machinery or tooling required. [0015]
  • It is yet another object of the invention to provide a hunters stand that includes an observation platform supporting a chair for the hunters conveniences. It is a further object of the invention to provide an observation platform that may be used by spectators of sporting events such as parades, auto races and the like which affords a complete and unobstructed view of the sporting event, and in which the apparatus is completely mobile as attached to the rear portion of a vehicle. [0016]
  • A mobile elevated viewing platform apparatus is disclosed for use with and transport by a standard multi-passenger vehicle. The apparatus includes a base assembly, the base assembly being adapted for reversibly mounting to the exterior of a passenger vehicle. Further, at least one mast having a lower end and an upper end is employed. An elevated viewing platform, is adapted for supporting at least one seat. The elevated viewing platform is supportable by the upper end of the telescoping mast. Finally, the mast is easily removed for transportation for vehicular travel or a second erect position for supporting the elevated viewing platform. In some applications, both a platform and accessory unit are provided. However, other applications disclose only an accessory unit without a platform, or only a platform without the accessory unit.[0017]

  • FIG. 2 shows the platform apparatus in the shortened [0037] position 37, as it would appear when the vehicle 24 is prepared for travel. In this position, the platform 26 has been lowered, and rests upon support 38, and the leveling leg 34 that was seen in FIG. 1 has been retracted from the surface of the ground. In the shortened position 37 shown in FIG. 2 the platform 26 rides only a few feet above the cabinet 32, and its reduced height lowers the center of gravity of the entire unit so as to provide stable and comfortable travel of the vehicle 24 to and from a sporting event, hunting site, or other place in which the apparatus will be employed. Furthermore, when the apparatus is used for hunting, the shortened position 37 as shown in FIG. 2 may be used when moving from one hunting location to another hunting location, either upon the same ranch or within a county or geographical hunting area.
  • FIG. 3 shows an initial [0038] loading winching position 40 of the invention in which a cable 41 attached to the first mast 23 is used to pull the platform 26 into an erect position. A winch system 42 may be used, in which the winch is either in the upper portion of the cabinet 32, or in the lower portion of the cabinet 32. The winch is located in the lower portion of the cabinet 32, and a pulley may be used in the upper part of the winch system 42. A pulley 42 a is only used during erection or initial loading of the first mast 23. In FIG. 3, the base assembly 22 may be seen which is comprised of a frame 43 that inserts into the hitch 63 just below the bumper 67 of the vehicle 24.
  • FIG. 4 shows a partially [0039] elevated position 50 of the apparatus of the invention in which the first mast 23 is in a vertical position, but the telescoping rails and platform 26 has not yet been raised to its operational height. Once the apparatus is in position as shown in FIG. 4, then the second mast 46 and seat 27 a may be raised (as shown in FIG. 5) to provide a seat 27 a at operational height. This seat 27 a is supported by the upper end 25 b of the mast. On the other hand, the lower end 25 a of the first mast 23 is seen just above the cabinet 32. Then, the next step in placing the apparatus of the invention in operational mode may be seen in FIGS. 6-8.
  • In FIG. 6, for example, an [0040] end view 52 of one embodiment of the invention is shown having seats 27 a and 27 b supported first mast 23 and the second mast 46. Furthermore, the adjustable cross-member 55 support the platform 26 for transportation configuration. Pulleys 53 a and 53 b support a cable 59 that is attached on one end to the platform 26 or deck 30, and at the other end to the winch system 42 (not shown in FIG. 6). Furthermore, pulley 53 c is supported at one end by the platform 26 and at the other end by the winch system 42 (not shown in FIG. 6). When the winch system 42 is activated, cable 59 and cable 60 are used to pull the platform 26 upwards into position.
  • Furthermore, in FIG. 6 a [0041] right accessory unit 57 and a left accessory unit 58 are shown at the lower portion of FIG. 6. A variety of modules are provided within the right accessory unit 57 and left accessory unit 58, which may include a television, stereo, spot light, telephone, DC/AC power inverter, coffeemaker, stove, sink, water tank, pump, generator, and winching system 42 (not shown in FIG. 6). This list is not exhaustive of all the accessories that could be provided within the invention, but is merely a listing of several examples. Furthermore, in some cases it would be possible to disengage one or more accessories and place them upon the platform 26 as for example, a television, stereo and the like. Supporting the apparatus shown in FIG. 7 are leveling legs 34 and 35. A refrigerator may be provided in the center as shown in FIG. 6.
  • FIG. 8 shows the apparatus in which the [0042] platform 26 has been raised to its fully elevated position and is ready for occupancy. Ladder 31 has been erected which leads to an opening (not shown in FIG. 8) in the bottom of the platform 26 and deck 30.
  • FIG. 9 shows the apparatus in the storage mode in which the [0043] base assembly 22 has been disengaged from the receiver portion 64 of the hitch 63. Furthermore, a center leg 61 is shown which provides stability and the opportunity for the apparatus to be placed into storage facility 62 shown in FIGS. 9 and 10. Importantly, when the apparatus is not to be used, it is relatively simple to disengage from the vehicle 24 and store the apparatus until the next hunting or sporting event, and it is not necessary to store any portion of the apparatus in the vehicle in between hunting or sporting events, which is highly desirable and convenient.
  • FIG. 11 shows an alternative embodiment of the invention in which the [0044] utility cabinet 32 is not used. Instead, the embodiment shown in FIG. 11 is second embodiment 100, which includes a base assembly 122, connected to a first mast 123 a, and a second mast 123 b to which the seat 127 a is attached. Further, a platform 126 supports a deck 130, and a ladder 131 is positioned below the platform 126. A seat 127 a is connected to the first mast 123, and supports 128 a-c is connected to the safety rail 129. Furthermore, a frame 143 is operably connected to the vehicle 124. Leveling leg 134 is also shown below the base assembly 122. The second embodiment 100 is particularly useful for sportsman who would like to have an elevated observation platform in a mobile configuration, but does not require outdoor living utilities/accessories as provided in the first embodiment shown in FIGS. 1-8, while still providing sporting options such as rifle sighting, skeet shooting, target practice and the like.
  • FIG. 12 shows yet a [0045] third embodiment 200 of the invention wherein there is no observation platform, but instead there is a mobile accessory unit which is useful for outdoor living, camping, etc. The third embodiment 200 is comprised of a utility cabinet 232 which would have accessories similar to that shown in FIGS. 7-8. Likewise, a leveling leg 234 supports the base assembly 222, and a frame 243 removably attaches to the vehicle 224 as shown in FIG. 12.
  • [0046] Utility cabinet 232 preferably comprises a hinged fold down unit in which the cabinet hinges at its lower edge and a back panel is lowered to reveal one or more accessories that have been previously described herein.
  • FIG. 13A shows a top view of the [0047] frame member 75 of the base assembly 43 that is shown in FIGS. 1-8. The frame member 75 comprises frame 43, which contains stabilizer bars 79 a and 79 b on either side of the frame 43. Furthermore, a draw bar 77 is provided for removable connection to a trailer hitch on a vehicle.
  • FIG. 13B is a cross-section cut-away as seen along lines [0048] 13 b-13 b of FIG. 13A. In FIG. 13B, a connection mechanism 72 is comprised of a receiver portion 64 of a hitch 63 into which a draw bar 77 is inserted. Although this standard method of hitching is available on most United States vehicles, any other suitable method for attaching the platform apparatus 21 to a vehicle could be used. For example, other hitching mechanisms are possible, in which other removable mechanical connections are made to the rear portion of a vehicle, and such apparatus would be within the scope and spirit of this invention disclosed herein.
  • FIG. 13C shows one example of one embodiment of a stabilizer bar [0049] 79 a (as shown in FIG. 13A) seen in a side view in which the upper flange 81 and lower flange 82 form a yoke 80 in the middle that is secured to the frame of the hitch on the vehicle (not shown). In some cases, a bolt or cotter pin could be inserted to connect upper flange 81 and lower flange 82 to the frame of the hitch on the vehicle.
